... Optical Isolator And Circulators In Black Optical isolators can block backflection and backscattering in the reverse direction at any polarization sate. It have low polarization mode dispersion(PMD),Polarization Dependent(PDL),Loss High Isolation...

... directions. by in one single optical fiber, analogous to the operation of an electronic circulator. An standard optical circulator is a three-port device that allows light to travel in only one direction...

... is like the optical circulator, they are based on the GRANOPT's faraday rotator. The circulator has three ports but the isolator has only two ports, the circulator can be treated as an isolator because the
